摘 要:A novel 70Si30Al alloy was prepared by the spray forming process for electronic packaging materials. The effect of the ratio of atomization pressure to metal melt mass flux rate (P/M) on the preforms and microstructures of the spray-deposited 70Si30Al alloy was studied. The results indicate that the P/M value has a considerable influence on the formation of the preforms and the optimal value is in the range of 0.209-0.231 MPa/(kg·min-1). The microstructure of the spray formed 70Si30Al alloy is fine and homogenous. The primary silicon phases distributing in the aluminum matrix evenly are fine and irregular. The aluminum matrix is divided into two groups: supersaturated α-Al phase or α-Al phase and Al-Si pseudoeutectic phase or Al-Si eutectic phase.
